Problems solved by technology

Second, the high-voltage electric field polarizes particles in the air flow and portions of the filter medium itself, causing the polarized particles to be attracted to polarized portions of the filter medium.
In addition, equipment downstream of the filtration system, such as the flow detector itself, a fan or a heat exchanger, may be damaged or otherwise negatively impacted if ions are allowed to precipitate downstream.
Although present devices are functional, they are not sufficiently accurate or otherwise satisfactory.

Embodiment Construction

[0024]Referring now to the drawings, where like or similar elements are designated with identical reference numerals throughout the several views, and referring in particular to FIG. 1, it illustrates one embodiment of a flow sensor. Flow sensor 100 may be used in numerous applications where the measurement of a fluid flow is desirable. In the present embodiment, the invention is discussed for use where the fluid is air. This is exemplary only. Those skilled in the art will be aware of uses and modifications for various fluid flows including liquid flows and gas flows. The present embodiments discuss the use of the present invention in the air for discussion only. While certain modifications may have to be made in order to operate in different fluids, those modifications fall within the present invention and are covered by the claims.

[0025]In traditional operating environments, a flow sensor may be required to operate accurately over a wide range of temperatures. In order to allow t...
